||The measurement of reverberation times in 230 classrooms of 30 schools in Germany and comparison of the results with the recommended reverberation times in the German standard DIN 18041 identified unsatisfactory acoustical conditions in one third of the classrooms. A low-cost method of noise control for noisy classrooms was developed which schools can easily install themselves. Ceilings were covered with soundproofing melamine foam panels 45 mm thick and additional sound-absorbing panels were placed on the walls to reduce the reverberation times of low-frequency noise. The easy-to-install sound control method was successfully applied in eight classrooms. More information on the sound control method for classrooms is available on the Internet: www.fluesterndesklassenzimmer.de
